The suspect, Dennis Anthony Perez, 48, of San Gabriel, was charged with two misdemeanor counts of vehicular manslaughter and one count of felony hit-and-run resulting in the injury or death of another person, according to officials with the Los Angeles County Superior Court.

Perez was arrested Tuesday morning after he was discharged from a Pasadena medical facility. The arrest came after an anonymous tip led San Gabriel police officers to the truck that was allegedly used in the hit-and-run.

The fatal collision happened on Del Mar Avenue and Live Oak Street shortly before 9:35 p.m. Oct. 26, in San Gabriel. Meiyu Li, 59, was pushing her granddaughter, Paisley Chen, 1, in a stroller in a crosswalk when a Chevrolet pickup truck struck them, police said. Witnesses saw the truck drive away right after.

Li and Chen were transferred to hospitals where they died.

San Gabriel police Capt. Fabian Valdez said Perez was arrested at least three times for DUI incidents in the past. It wasn’t immediately known whether he was under the influence of any substance during Friday’s hit-and-run.

Perez is due back in court Dec. 4.

His bail is set at $250,000.

Perez’ defense attorney, Marlon Lewis could not immediately be reached for comment.
